Gentoo Linux Security Advisory

Title: PowerDNS: Multiple vulnerabilities (GLSA 200812-19)
Severity: normal
Exploitable: remote
Date: December 19, 2008
Bug(s): #234032, #247079
ID: 200812-19

Synopsis


Two vulnerabilities have been discovered in PowerDNS, possibly leading to a
Denial of Service and easing cache poisoning attacks.


Background


The PowerDNS Nameserver is an authoritative-only nameserver which uses
a flexible backend architecture.


Affected Packages

Package: net-dns/pdns
Vulnerable: < 2.9.21.2
Unaffected: >= 2.9.21.2
Architectures: All supported architectures


Description


Daniel Drown reported an error when receiving a HINFO CH query
(CVE-2008-5277). Brian J. Dowling of Simplicity Communications
discovered a previously unknown security implication of the PowerDNS
behavior to not respond to certain queries it considers malformed
(CVE-2008-3337).


Impact


A remote attacker could send specially crafted queries to cause a
Denial of Service. The second vulnerability in itself does not pose a
security risk to PowerDNS Nameserver. However, not answering a query
for an invalid DNS record within a valid domain allows for a larger
spoofing window on third-party nameservers for domains being hosted by
PowerDNS Nameserver itself.


Workaround


There is no known workaround at this time.


Resolution


All PowerDNS users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-dns/pdns-2.9.21.2"
